Device for manufacturing easily demolded wood-plastic formwork for building

Abstract

The invention relates to a device for manufacturing an easily demolded wood-plastic formwork for a building. The device comprises a wood-plastic blank plate forming mechanism, wherein wood strips areintegrated into a plastic body through the wood-plastic blank plate forming mechanism to form a wood-plastic blank plate. The device further comprises a needling exhaust mechanism, a calendering and leveling four-roller machine, a shallow layer heating mechanism, a finishing and calendering mechanism, a shallow layer rapid heating mechanism before pasting films, and a film feeding and pasting mechanism which are sequentially arranged in the processing direction; the discharging end of the needling exhaust mechanism is connected with the discharging end of the wood-plastic blank plate forming mechanism; and the needling exhaust mechanism comprises a needling conveying roller, a needling lifting plate driven by a needling lifting cylinder is installed above the needling conveying roller, anda plurality of inserted needles are arranged on the bottom surface of the needling lifting plate. The surface of the wood-plastic building formwork produced by the device is smooth and clean, the process of formwork removal in construction is not difficult, and the process of formwork cleaning does not need to be added when the formwork is reused.

Description

technical field [0001] The invention relates to production equipment for building formwork, in particular to a complete set of film-attaching equipment for manufacturing wood-plastic formwork for construction that is easy to release, so as to achieve the goal of high smoothness of the wood-plastic formwork. Background technique [0002] At present, in the production process of the traditional wood-plastic building formwork extrusion calendering method, its products are made of wood powder as an additive material, resulting in a very rough surface of the wood-plastic building formwork produced by the extrusion calendering process. The demoulding construction is difficult, and the surface layer of the wood-plastic building formwork has dried and solidified residual building concrete on the surface after the formwork is removed, which increases the workload of cleaning the wood-plastic building formwork during repeated use. The existing wood-plastic building templates used in c...
